2020-01-27Update package locations.Adin Scannell
Because the abi will depend on the core types for marshalling (usermem, context, safemem, safecopy), these need to be flattened from the sentry directory. These packages contain no sentry-specific details. PiperOrigin-RevId: 291811289

2019-06-05Implement dumpability tracking and checksMichael Pratt
We don't actually support core dumps, but some applications want to get/set dumpability, which still has an effect in procfs. Lack of support for set-uid binaries or fs creds simplifies things a bit. As-is, processes started via CreateProcess (i.e., init and sentryctl exec) have normal dumpability. I'm a bit torn on whether sentryctl exec tasks should be dumpable, but at least since they have no parent normal UID/GID checks should protect them. PiperOrigin-RevId: 251712714
